HAMMER.

SPECIFICATION forming part of Letters Patent No. 468,191, dated February2, 1892.

Application filed October 21,1890. Serial No 368,772. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR CHAMBERS, of \Villiams Bridge, in the countyof Westchester and State of New York, have invented a new and usefulImprovementin Hammers, of which the following is a full, clear, and eX-act description.

Myinvention relates to an improvementin ham mers, cspeciallycarpentershammers, and has for its object to provide a hammer with a sidestriking-face of an elastic or a slightlyelastic material, the said sideface being especially adapted for striking the handles of chisels orsimilar tools in cutting mortises and performing other work for whichsuch tools are employed, thus combining in one tool a mallet and ahammer, one in no wise interfering with the other, and providing a han1-mer with a means Wherebya blow upon a wooden handle will not injure thesame.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outinrthe claims. i Reference is to be had to the accompanymg drawings,forming a part of this specificatlon, in which similar figures andletters of reference indicate corresponding parts in all the views.

Figurel is a side elevation of a hammer provided with my improvement.Fig. 2 is a vertical section through the hammer, the section being takenon the line 2 2 of Fig. 1. Fig. 3 is a sectional view of ahammer-head,illustrating a modified form of the improvement.

The hammer 10 is of the usual construction, including the format-ion ofthe eye 11. In the side of the hammer an opening 13 is produced,preferably circular and extending through from the outer face into theeye of the hammer, as best shown in Fig. 2. The side Wall a of theopening is chamfered or beveled from the out-er face of the hammerinward to the eye, whereby the diameter of the opening at the eye ismuch greater than at the outer side face of the hammer.

Two disks 14 and 15 are usually employed to fill the opening, whichdisks are made of an elastic or a slightly-elastic material, such asrubber or leather. Each disk represents, practically, the frustum of acone, the outer disk being the thicker and of such diameter that itneatly fits into the opening and extends some distance beyond the sidesurface of the hammer, as shown at a. Theinner face of the inner disk isslightly tapered, and the lower edge 16 is thinner than the upper edge17, the taper being gradual, and the inclination of the tapering surfaceis such that when the disk is fitted into the opening in engagement withthe outer disk its lower inner face will be flush with the wall of thehammereye be low the opening and project beyond the wall above theopening. The disks are inserted in the side opening from the hammer-eye,and are securely held in place by thehandle 18. \Vhen it is driven inthe eye and wedged, as by means of the conical form of the opening andthe chamfered periphery of the disks, the latter cannot escape outwardand the handle prevents them from droppinginward.

The handle in entering the eye readily passes the lower edge of theinner disk; but as it reaches the upper edge it presses firmly upon theupper projecting inner surface of the disk, thereby preventing the samefrom turning. It will be understood that instead of using two disks, asillustrated, a single disk only may be employed, and that instead ofextending the side aperture through to the eye of the hammer a recess 19may be substituted therefor, having undercut walls, the elastic materialbeing forced into the said recess.

l'Iavin g thus described my invention, I claim as new and desire tosecure by Letters Patent- 1. A hammer-head provided with a side openinghaving beveled walls and extending through to the eye, and an elastic ora slightly elastic plug inserted in said opening and essentiallyconforming to the contour thereof, as and for the purpose specified.

2. The combination, with a hammer-head provided with a side openingextending through to the eye and having beveled Walls, of an elastic ora slightly-elastic plug fitted in the said opening, the inner face ofsaid plug being beveled, and a handle securing the plug in position inthe opening, as and for the purpose specified.
